Most cataract operations are uneventful. A small minority are not. What happens after a complication is determined less by surgical skill and more by the structure of the provider system in which the operation took place.
The Common Serious Complications
Posterior capsule rupture and dropped nuclear fragments occur in approximately 1-2% of UK cataract operations and represent the commonest serious intraoperative complication. National Ophthalmology Database analysis of 55,567 operations identified specific risk indicators, increasing age, glaucoma, dense or white cataract, small pupils, axial length over 26 mm, and certain medications, but also showed that complications occur in even technically excellent hands at predictable rates.¹ The standard management is prompt vitreoretinal surgery to remove the retained material, and earlier intervention is generally associated with better visual outcomes and lower rates of secondary complications.²
Endophthalmitis, the most serious post-cataract infection, occurs at a rate of approximately one in a thousand operations in well-run modern series. The ESCRS multicentre study established the protective effect of intracameral antibiotic prophylaxis and provided the basis for current protocols across UK private and NHS practice.³ Acute endophthalmitis presents within the first week and requires immediate vitreoretinal involvement; delayed-onset endophthalmitis presents weeks or months later and is often associated with low-virulence organisms.
Pseudophakic retinal detachment is an uncommon but recognised late complication; it requires vitreoretinal repair and carries a meaningful risk of incomplete visual recovery if treatment is delayed.
Why The Provider System Determines the Outcome
For each of these, the practical question for the patient is the same: who manages the complication, in which system, on what timeline, and with what cost implication? In a consultant-led private system with integrated vitreoretinal cover, the patient is managed within the same clinical team. In a fragmented pathway, the complication generates an external referral, most often to the NHS, and the timeline becomes the timeline of an external waiting list.
Who This Is Not For
This page is not an exhaustive guide to every possible complication of cataract surgery. It addresses the three commonest serious complications and the structural question they share. Patients experiencing acute symptoms, sudden visual loss, severe pain, or a red and inflamed eye after surgery, should contact their surgeon urgently rather than read further.
Clinical Takeaway
Complications after private cataract surgery are managed differently depending on the provider system. The probability of a complication is low; the consequence depends on what surrounds the surgeon.
